Abstract
Objective. A dual case is reported of a father and daughter, both with psychotic symptoms.
Case. The 31-year-old daughter was diagnosed with undifferentiated schizophrenia. Her personal history suggests that the onset of schizophrenic symptoms preceded her hospitalization by 9 years. She did not receive any regular treatment. Her father has never been treated psychiatrically. The presence of his psychiatric symptoms was found during the family history taking.
Commentary. Both patients shared some of the delusional content, which contributed to the schizophrenic daughter decision to consent to treatment.
